Buick Excelle code128 means the hood is not properly closed. Here is more extended information about the Buick Excelle: 1. Basic Introduction: The Buick Excelle is the fourth model produced on General Motors' latest global platform following the new Regal, new LaCrosse, and Enclave. The older Buick Excelle originated from the Opel Astra and was built on the GM Global DeltaⅡ platform. The all-new Buick Excelle was officially launched on March 2, 2015. 2. Basic Concept: The Excelle not only perfectly interprets the inherent spirited temperament, sharp and tough lines, and driving feel of this five-door coupe but also reflects the talent, wisdom, and bold, decisive style of the new generation of striving youth.

Last time I drove the Excelle, the code 128 also popped up, which is actually the maintenance reminder light! This code is specifically designed to remind you to change the engine oil—Buick's design is quite thoughtful. It usually appears if you haven’t serviced the car for over 5,000 km. No need to panic if the yellow light flashes, but if the red light comes on, don’t drive. The key point is that this reminder light won’t turn off by itself. After changing the oil, you need to manually reset it: Turn off the engine, press and hold the button on the right side of the dashboard, turn the key to the power-on position without starting the engine, and wait for the progress bar to complete. Many car owners assume the light will turn off after an oil change, only to make a wasted trip to the repair shop.

What Causes Car Door Locks to Fail?

Here are the specific reasons why car door locks may fail to engage: 1. Remote lock malfunction or antenna aging: If you're using a remote key to lock the door, it's highly possible that the remote lock is malfunctioning or the antenna of the car's remote transmitter has aged, causing the remote key to be ineffective. In this case, you can use the spare mechanical key to lock the door. 2. Magnetic field interference: Strong magnetic field signals around the car can interfere with the operation of the smart key, which uses low-intensity radio waves, making it unable to function properly under magnetic interference. 3. Door lock jammers: If the car frequently fails to lock remotely in a particular location, the owner should be wary of door lock jammers. Criminals may use a radio signal jammer that emits electromagnetic waves at the same frequency as the lock signal, thereby blocking the electronic code of the car's central lock and causing it to temporarily malfunction.

Can a Private Car Last for 30 Years?

If driven 20,000 kilometers annually, a car can last for 30 years. Here are relevant details about vehicle lifespan: 1. During usage: Components gradually wear out with frequency of use, and performance declines over time. 2. Vehicle inspection: Starting from the 15th year, biannual inspections are required; from the 21st year, this increases to quarterly inspections. 3. Component aging: Failed inspections due to performance deterioration will mandate scrapping. With increasingly stringent environmental policies and emission standards, non-compliant vehicles will receive yellow labels prohibiting urban driving, effectively requiring disposal. 4. Long-term ownership: Declining performance leads to rising maintenance costs. Insurance premiums must be paid annually, with claims history significantly impacting subsequent year's rates.

Can the car clutch control the speed?

The car clutch can indeed control the speed. The clutch is a tool that connects or disconnects the engine from the transmission system. While it does not directly change gears, the degree of engagement between the engine and the transmission varies as the clutch is lifted or depressed, thereby allowing speed control. Here are methods for controlling speed with the clutch: 1. Press the clutch quickly and release it slowly: The most effective control method is to use the ball of the foot suspended in mid-air to avoid slipping or misalignment. 2. Be able to sense the semi-engagement stroke for starting on flat ground and slopes: Get accustomed to starting with semi-engagement by first lifting the clutch to the semi-engagement point and then releasing the brake.

What Gear Should the Car Be in When Waiting at a Red Light?

When waiting at a red light, shift the car into N (Neutral) gear and engage the handbrake or hold the brake pedal. Below is an introduction to the relevant driving gears of a car: 1. P (Park) gear is the parking gear: When the gear lever is in the P position, the transmission is in neutral internally, but the output shaft is mechanically locked. At this time, the car will stop in place even if the brake is not pressed, and it is generally used when the car is parked for a long time. When shifting into P gear, the car must be completely stationary. Do not shift into P gear when the car has not come to a complete stop, and always engage the handbrake. When parking on a slope, first engage the handbrake and then shift into P gear. 2. R (Reverse) gear is the reverse gear: When the gear lever is in the R position, the rotation direction of the transmission output shaft is opposite to that of the engine, allowing the car to move backward. When shifting into R gear, the car must be completely stationary. Do not shift into R gear when the car has not come to a complete stop. 3. N (Neutral) gear is the neutral gear: When the gear lever is in the N position, the gears inside the transmission are in a freewheeling state, and the clutch is not engaged, so the load on the transmission is minimized. N gear is generally used for short stops, such as waiting at a red light. Additionally, when the car is being towed, the transmission should also be in N gear. 4. D (Drive) gear is the driving gear: When the gear lever is in the D position, the gears inside the transmission automatically switch between the lowest and highest gears according to factors such as vehicle speed and throttle opening, based on the preset shifting pattern. In most cases, D gear can be used for driving.

Will Polishing Make Car Paint Thinner?

Polishing car paint will make it thinner. Here are the specific details about vehicle polishing: 1. Principle: Polishing involves grinding away the outermost "clear coat layer" of the car paint. After multiple polishing sessions, the clear coat layer becomes thinner, weakening its protective effect on the base color layer of the paint. Therefore, it is recommended to apply a glaze sealant after multiple polishing sessions, which essentially replenishes a new clear coat layer. 2. Application: Car polishing is a step in the car detailing process, performed before waxing, glazing, or coating to prepare the car's surface. This is because glazing or coating requires prior polishing, and only a finely polished car can achieve a mirror-like finish. This step is essential for the glazing process. Without proper polishing, the car paint surface remains uneven, and the glaze sealant will not last long, failing to provide long-term adhesion—essentially making it no different from regular waxing.
